Quandaries and Queries


I have 6 acres of concrete that is 3 feet thick the aprox. weight of 1 cubic yard of concrete is 4024 pounds I am trying to find out how much my 6 acres weighs. fortunately my concrete is 3 feet deep.

Please Help My Boss really needs this answer and I don't know if my equations are flawed. Thank you very much for your help.



Hi Jordan,

There are 43560 square feet in an acre so 6 43560 = 261360 square feet in your 6 acres. One square yard is 3 feet by 3 feet and hence 9 square feet, thus your 6 acres is 261360/9 = 29040 square yards.

The concrete is 3 feet thick which is 1 yard thick so the volume of concrete is

29040 1 = 29,040 cubic yards.

Each cubic yard weighs 4024 pounds so you have

29,040 4,024 = 116,856,960 pounds of concrete,

which is 58,428 tons.
